使用组合列访问数据库填充组合框
Fill Combobox with combined columns access database
如何从我的 access 数据库 "contacts.accdb" 填充组合框中组合列 "Firstname" "Lastname"？我已经将 dataset +datagridview 加载到项目中的另一个表单中..
一个简单但完整的例子：
Dim con as New OledbConnection = connectionstringhere
Dim cmd as New OleDbCommand("Select * from tablenamehere",con)
Dim dr as OledbDataReader=cmd.ExecuteReader
While dr.read
Dim FnameAndLname as string = dr(0).ToString + " " + dr(1).ToString 'Assuming the FirstName is the 1st and the LastName is the 2nd Column of the table
MyConboBox.Items.Add(FnameAndLname)
End while
希望这对您有所帮助:)
